New product introduction:
1: The output current is up to 3A, and the long-term operation is 2.1A. The margin is sufficient.
2: Designed with a new solution, the circuit design does not require electrolytic capacitors and tantalum capacitors
3: Improve conversion efficiency. Reduce heat.
4: small volume, 20 (length) * 11 (width) * 5 (height) mm.
5: Low quiescent current, quiescent current 0.85 mA. Connected to the car battery without a switch, can be connected to the cigarette lighter line, or ACC power line.
6: The output is integrated with adjustable and fixed voltage. The fixed output is not required to be customized. It can be directly soldered on the board. It is very voltage-sensitive and can be adjusted by potentiometer. It is very versatile.
7: Integrated enable port, default is working mode, low level is off, which brings convenience to control
